3 Claims. (Cl. 15-176) This invention relates to hair brushes, and moreparticularly to brushes for toilet sets, and still more particularly tobrushes in which the brush assembly may be interchangeably separated forcleansing.

It is an object of my invention to provide a brush forming an element ofa toilet set, usually composed of a comb, a brush, and a hand mirror,and to provide a frame combined with a brush head assembly which may beremovably associated with the frame. More specifically, it is an objectof my invention to provide a re movable brush head for a frame whichinterchangeably permits the frame to have separated a brush head toinstall a selected brush head or to remove the brush head for cleansingwithout injuring the brush frame.

More specifically, it is an object of my invention to provide a handbrush usually forming a part of a toilet set in which the frame is madeof delicate materials such as cast materials, upon which machiningoperations cannot be economically performed, and to include forcombination therewith a removable brush which is self-soilicient inproviding removable attaching means for engagement with the frame,thereby limiting all of the machining operations to the more sturdilyconstructed brush, to permit simple metal stampings or casting toconstitute the frame.

To attain these objects and such further objects as may appear herein orbe hereinafter pointed out, i make reference to the accompanying drawingforming a part hereof, in which- Figure l is a plan view of a brush inaccordance'with my invention;

Summarizing my invention, I provide a frame of simple contour as made bydie-casting or metal stamping, and which includes a rim forming anoverhang which is susceptible of die-casting or stamping, and removalfrom the mold or form, the frame rim serving as the means for.rernovably attaching a brush head which is self-contained with regardto attaching means so that any machining or manufacturing processes arereserved for the brush head which may be removed from the frame quicklyfor cleansing, without damaging the frame carrying the ornamental finishor assembly of backing elements.

of another embodiment, using a comb, and a brush, inter alia. Inaccordance with my mvention, the frame contemplated by me includes aframe portion 12 having an overhanging rim 13 and a socket 14 of acontour which is readily susceptible of production by forming in a moldby molding or punching.

die-casting, extrusion, powder Such materials as .cast bronze and zincalloy, metallic and plastic molding powders are exemplified assusceptible of ready molding to produce a piece which comes out from themold more or less in finished condition, not only requiring littlemachining but upon which machine operations are not economically carriedout. Frame .made of thin sheet metal or plastic sheet channels, ashereinafter described, may likewise benefit from my invention.

The frame has an open throat portion 15 into which an ornamental back 16may be pressed frictionally, and where made of non-metallic materials,may be adhesively combined therewith. A frame so provided has a :brushhead 17 removably associated therewith, and for this purpose a wooden orplastic plug 18, or brush back, has assembled therewith the bristles 19in the usual manner.

The periphery of the plug or brush back is formed withan overhangingledge 20, forming :a shoulder, and side walls 21 to clear the rim 13 onthe side edges 22 and bottom edge 23. The head portion 24 is formed withan extension lip 25. The head 24 is arranged to abut the rim 13 at itshead portion 26. The base 27 of the brush back is provided with a latch28and attached to the brush back by extending the branch 29 thereof intoengagement with the brush back .and riveting the same by rivets 30 vorother fastening means. The latch has a resilient tongue 31 disposed bythe loop 32 into a slot 33 formed in the brush back. A thumb .button '34may press the pawl 35 on the branch 31 to and from the brush backperiphery. The pawl has a camming edge 36 for purposes which will nowappear more clearly.

With a construction as described, the brush back may be removablyassembled with the frame by first extending the lip 25 beneath the rim13 at the top portion, to bring the edge 24 into abutting relation atthis point. Thereupon the plug is guided to have theside walls pass therim 13 and seat the ledge 20 on the outer face of the rim. In thisposition .the cammingedge 36 of the latch rides upon the rim portion 37and engages on the overhanging Wall 38, holding .the brush againstdisplacement. It will be seen that inward displacement and conformingposition are provided by the ledge 20, whereas outward displacement isprevented by the lip 25 and the pawl 35 of the latch engaging the rim asdescribed.

To remove the brush back for cleansing without subjecting the frame tothe cleaning operations, only press the thumb against the thumb button34 to direct the branch 31 inwardly within the slot 33, disengaging thepawl 35 from the rim portion 37. This movement serves to tilt the brushback out from the socket formed Within the frame about the anchored lip25 as a fulcrum.

While I have shown in the embodiment illustrated "in Figures 1 to 4,removable engagement of the frame and brush back in which the rim servesas a stop for an overhanging ledge, I may provide a frame and brush backassembly in which the brush back conforms to the frame.

In the embodiment illustrated in Figures 5 to 7, I promold. In thisconstruction an ornamental back 16a may be assembled for frictional oradhesive fit at the periphery, i

as in the prior embodiment.

one need itself readily to proper :draft from a In the constructiondescribed I provide a brush head 17a, whose peripheral walls on the side22a and bottom 23a conform to the rim 13 previously described. The head25a overlaps an extension lip 26a formed in the frame and having arectilinear edge conforming to a slot 27a, cut or otherwise formed atthe top edge of the brush back; In diametrically opposed position, theback is formed with a latch 28:: having a branch 29a,-as in the priorembodiment, for attachment by rivets or screws 30a.

The branch 31a terminates in a thumb button 34a. At a position spacedfrom the thumb button 34a, 1 provide a locking lug 35a, shaped toconform to the rim portion 37a.

It will be observed that with this construction, attachment of the brushback 17a is efiected first by directing the lip 26a into the slot 27aand then pressing the bottom edge over the rim 37a. The lip 32a cams thebranch 31a over the rim 37a until the locking lug 35a engages the edge,top, and side walls of the rim portion 37a. In this form ofconstruction, the brush head 17a is held against inward as well asoutward displacement by the cooperating locking means formed at the topand bottom edges. For removal of the brush back, pressure on the button34a upwardly, serves to tilt the branch 31a to clear the rim 37a andtilt the brush head out of its socket.

. By making the latch branch 31a resilient, it urges the lip 25a and lugengaging slot 27a into engaging position against accidentaldisplacement.

In Figures 8, 9 and 10 I have illustrated my invention as applicable toa brush frame which is made of thin sheet metal channels or relativelyfragile plastic sheeting in the form of channels which, of itself, iseconomically made thin and would ordinarily not be capable of resistingthe stresses involved in manipulating the brush during use. In thisconstruction a frame 40 of thin sheeting material, such as metal ofgenerally U-shaped construction, has branches thereof 41 and 42 joinedby a ferrule 43 to house the ornamental back 44 and a stiffening back 45between the front overhang branch 46 and the rear overhang branch 47 ofthe channel. The back 45 is dished and has an upstanding rim 48 whichextends from the front overhang branch 46 rearwardly to engage theornamental back 44 and press or wedge the rim of the ornamental back 44against the rear face overhang branch 47. The back 45 provides a socket49 for receiving the brush back. It likewise rigidifies and stiflens theframe assembly, holding the frame to the handle 50 by a pull rod 51whichis riveted to the back 45 and extends through to the ferrule andthe branches 41 and 42 into the handle.

Anchor means, which form no part of the invention herein, retain theterminal portion 52 of the pull rod within the handle 50.

The pull rod 51 extends into the handle by passing through a cutout 53,an upper wall of which forms a seat 54 adjacent the front overhang 46.The upper portion of the back 45 is formed with a cutout 55, having awall transverse of the back to form a seat 56. The extensiveness of theslot 55 is suflicient to receive the lip 25 of the brush head 17,described in the prior'embodiment.

With the construction described, the brush back 17 may be assembled withthe frame shown in Figures 8, 9 and 10 by extending the lip 25 into theslot 55, until the shoulder 20 abuts the outer face of the overhang 46.When the ledge 20 is pushed down fully within the socket 48, the rearportion carrying the latch 28 rides into latching position which, in thelimiting position, brings the latch tooth 35 into locking engagementwith the seat 54 of the slot 53.

By the construction, thin sheet metal channel frames may readily beemployed to support a removable brush and provide the rigidity ofassembly in forming required of a hair brush. The brush further clampsthe frame to the brush back to provide a sturdy construction in a veryeconomical manner.

As in the prior embodiments, the'relatively fragile,

ornamental sheeting material of which the frame is made requires nomachining operations in order to afiord adequate support for theremovable brush head. The em-,

facturing operations above described, while providing ready means forattachment of the brush back. The resiliency of the latching meanscarried by the brush head allows for wide tolerances in size between thebrush back and frame, without sacrificing rigidity of assembly. 7Cooperating elements of frame and brush head thereby permit of theformation of highly ornamental frames, withr out sacrificing therequisite strength, yet affording ready removal of the brush head forcleansing purposes.

The present application is a division of my application Serial No.145,550, filed February 21, 1950, now abandoned.
